Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a master station device in a remote monitoring and control device.

[Conventional technology]

In general, the objects that are monitored and controlled by remote monitoring and control equipment are wide-ranging and vary in scale, so the monitoring and control panels of the master station have traditionally been custom-made to suit each system. There is. In recent years, as general-purpose video display devices such as CRTs have come into practical use, monitoring panels have become able to display freely using fixed hardware, but control panels are still custom-made as before. Used a lot.

The main reasons are as follows.

First, there is a method of displaying the device number on the video display and selecting the corresponding number using a general-purpose switch such as a numeric keypad, but this method requires multiple steps and is cumbersome.

Secondly, compared to status display, control actually has a direct impact on the operation of the system, and the emphasis is on preventing erroneous selection and control of equipment, so the equipment and selection switch are A one-to-one correspondence scheme is preferred.

In other words, the control panel will consist of fixed hardware. For remote monitoring and control, a selection card corresponding to each device is prepared in advance, and the operator inserts the card into a card reading device to connect the monitoring panel and control panel to a general-purpose video display and a general-purpose card reader. It is fixed using a device.

The control panel will also consist of fixed hardware.

Furthermore, Japanese Patent Application No. 137321/1984 is a master station device for a remote monitoring and control device that does not have the above-mentioned problems.

[Problem that the invention seeks to solve]

Since the master station device of the conventional remote monitoring device is configured as described above, the operator has to find the selection card of the corresponding device and insert it into the card reader every time it is operated, which causes problems such as very cumbersome work. This invention was made to solve the above-mentioned problems.It is a fixed hardware that integrates the monitoring panel and the control panel, and the operator can touch the touch panel installed in front of the video display. To provide a master station device for a remote monitoring and control device that can easily and reliably select and control a corresponding slave station and a corresponding device just by touch operation.

[Means for solving problems]

A master station device for a remote monitoring and control device according to the present invention can be used for various purposes by having a video display and a touch panel installed in front of the device.
The operator can perform control operations while visually confirming the diagram of the slave station and the status of the equipment, as in the case of conventional custom-made monitoring and control panels.

[Effect]

The master station device of the remote monitoring and control device in this invention looks through the touch panel on the video display, and when the operator touches the poke point or 'a D symbol with his finger, the control circuit receives input from the touch panel. Based on the coordinates of the position touched by the finger, the base station and device are selected and a control code is transmitted to the corresponding slave station.

[Crying ≠ Examples]

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, O is a master station, 1, 2 . ......,N
are slave stations, and L, , L, . . . tLN are transmission paths connecting the master station O and each slave station 1゜2, .

In addition, VD is the video display at the master station O, TP
is a touch panel installed in front of the video display VD, and CC is a control circuit.

The internal CP in the control circuit CC is a central processing unit, SM
is a status memory that constantly updates and stores its contents according to the status and telemeter of each slave station device, PM is a pattern memory that stores fixed patterns such as diagrams of slave stations displayed on the video display VD, and CO is a An output control circuit that controls the output to the video display VD, CI is an input control circuit that analyzes the coordinate input signal of the position touched by the operator on the touch panel TP, and I and I are lines for transmitting and receiving signals with each slave station. It is an interface circuit.

Next, the operation shown in FIG. 1 will be explained. First, each slave station device R1, R2..., RN constantly inputs the status of the monitored control equipment and telemeter data, and transmits the transmission line L1-L.
2...Transmit to master station O via tLN.

In parent/child 0, when the line interface circuit LI inside the control circuit CC receives a signal from each slave station, the central processing bag [CP transmits this to the state memory SM, and the state memory S
M receives this and updates or stores the contents.

Poke points for selecting slave stations are always displayed on the video display VD, and the transparent touch panel TP
It is possible to visually see through it.

(It may not be displayed all the time, but may be displayed by the operator's switch-on operation.) Figure 2 shows the slave station selection screen displayed on the video display VD and visible through the touch panel TP. As an example of a poke point, a normal CRT can be used as a video display VD, but a projection type (projection from the inside) video display has a larger screen and is more effective.

Further, in the case of a liquid crystal display, it is suitable for the master station device of the present invention because the space factor of the monitoring control panel and the positional relationship with the touch panel TP, which will be described later, can be accurately determined.

The touch panel TP is a transparent panel attached very close to or in close contact with the front surface of the video display VD, and when it is touched with a finger, its position coordinates are input to the input control circuit CI in the control circuit CC. FIG. 3 is a configuration diagram showing an example of the touch panel TP, and an enlarged view with a portion thereof cut out is shown on the right side.

When a finger is touched, a potential is generated due to the contact resistance, and the coordinates of the position touched by the finger can be detected based on the scanning timing.

Returning to Figure 1, if the poke point for selecting a slave station as shown in Figure 2 is displayed on the video display VD, and the operator touches the NORT HS/S point with his/her finger, the touch panel Input control circuit CI from TP
The coordinates of the position where the poke point of N ORT HS/S is displayed are inputted to , and the central processing unit CP calculates the N ORT HS/S from the position coordinates detected by the input control circuit CI.
Confirm that S has been selected, and send the diagram of N ORT HS/S from the pattern memory PM to the output control circuit CO, and the diagram of N ORT H from the state memory SM.
3/S reports the status of the equipment. Output control circuit CO is N
A diagram of the ORT HS/S and the status of the equipment (red for closed status, green for open jFA, etc.) are superimposed and displayed on the video display VD.

FIG. 4 is a diagram of the N0RTI-I S/S and an explanatory diagram of the equipment status.

In Fig. 4, 52R1 and 52R2 are power receiving circuit breakers;
52P1, 52P2 are transformer primary circuit breakers, 52S1,
52S2 is the transformer secondary breaker, 52T is the busbar connection breaker, 52F1.52F2゜...52F6 is the feeder breaker, and the corresponding symbol is red when the corresponding equipment is closed, and open. If the status is correct, it will be displayed in green. CL,
OP is a poke point for giving commands for opening/closing control to be described later, and R8 is a reset poke point for returning the screen to the always-displayed slave station selection poke point.

An example of operation will be described when the power reception breaker 52R1 is currently in an open state and the operator wishes to close (turn on) it. First, the operator should check the power receiving breaker 52R, which is displayed in green.
When the symbol 1 is touched, the coordinates of the position where the symbol is displayed are input to the control circuit CI from the touch panel TP, and the central processing unit CP selects the power reception breaker 52R1 based on the coordinate detection result of the input control circuit CI. This is confirmed and a signal to that effect is sent to the output control circuit CO. In response to this, the output control circuit C○ performs a confirmation display on the video display VD to confirm that the power reception breaker 52R1 has been selected. Confirmation display methods include flickering the corresponding symbol or device number, or changing the color. The operator confirms that the power receiving breaker 52R1 has been selected by the above confirmation display, and then touches the close control poke point CL on the right side of the screen to close the touch panel TP.
The corresponding position coordinates are inputted to the input control circuit CI from
Sends the 2R1 close control code.

If the first slave station 1 is N0RTHS/S, the control code is transmitted to the slave station R3 via the transmission path L1, and the slave station R1 receives it and verifies and decodes the code, and the corresponding device 52R
A close control command is issued to 1.

The state in which the power reception breaker 52R1 is turned on is the slave station R2.
The slave station R1 transmits this to the master station p via the transmitter L□. In the master station 9, the line interface circuit LI in the control circuit CC receives a signal to turn on the power receiving breaker 52R1, and the central processing unit CP stores the signal in the state memory SM.
The status is updated and stored in the status memory SM, and is also transmitted to the output control circuit C○, which changes the corresponding symbol on the video display VD from green to red.

The operator confirms that the power receiving breaker 52R1 of the NORT HS/S is turned on by the above operation, and when he touches the reset poke point R8 at the bottom right of the screen, the position coordinates are displayed in the input control circuit CI from the touch panel TP. In response to this, the central processing bag @CP instructs the output control circuit C○ to display the poke point for slave station selection that is always displayed. (This slave station selection poke point and its accompanying diagram are also puttered and stored in the memory PM, and can be displayed on the video display VD via the output control circuit CO as necessary.) We have explained the case where the equipment on the slave station responds to the control signal from the remote station, but another important operation of the remote monitoring and control device as the master station is the display and confirmation of automatic status changes of the equipment on the slave station. There is an operation, and this operation can also be performed as follows using the same configuration.

If the power reception breaker 52R1 automatically shuts off at N0RTHS/S, the shutoff state is input to the slave station device R1 of the slave station 1 and transmitted to the master station O via the transmission path L1. In the master station 0, the line interface circuit LI between the control circuits CC receives this, and the central processing unit CP updates and stores the contents of the state memory SM, and detects the state change. There is a method based on transmission, and a method based on comparison with the depressed state of the state memory SM. ), flicker the corresponding slave station (N0RTHS/S in this case) among the poke points for slave station selection that are constantly displayed via the output control circuit C○ (in this case, 1. Alarms such as bells are also used to alert the user.Also, in the case of a method in which the poke point for selecting a slave station is output by the operator's switch-on operation, a display should be automatically displayed in the event of an automatic status change. ) When the operator touches the poke point of the flickering NORT HS/S, the coordinates of the corresponding position are input from the touch panel TP to the input control circuit CI, the central processing unit CP confirms this, and the coordinates are sent to the output control port CO. Flicker - Gives an instruction to stop flickering. Note that it is also possible to separately provide a dedicated poke point for commonly checking status changes for all devices displayed on the screen and stopping flickering.

In addition, in the above embodiment, the balk points hC,L of opening/closing control
, We explained that when an operator touches ○P, a control code will be immediately transmitted to the corresponding device of the corresponding slave station, but considering the importance of control operations, we further confirmed the control operations that will be performed from now on. It is also possible to run it above.

FIG. 5 shows an example of the display screen of the video display VD in that case.

The difference between Fig. 5 and Fig. 4 is that there is a poke point Ex that gives execution instructions below the opening/closing control poke point CL, OP, and the operation is also at the opening/closing control poke point CL or ○P. Even if touched, the control code is not immediately transmitted, but the poke point CL or ○P is flickered to confirm the control operation, and the poke point E for execution command is confirmed.
Touching x transmits the code of the confirmed control operation.

In addition, the slave station and device selection can be confirmed using the control circuit CC of the master station 0.
In addition to the method of only performing the selection code, there is also a method of transmitting the selection code to the corresponding slave station and performing the selection code based on the response.

Further, the opening/closing control can generally be extended to raising and lowering the voltage, etc., and of course also includes control such as stopping the operation midway. In that case, just add a third poke point.

〔Effect of the invention〕

As described above, according to the present invention, the monitoring panel and the control panel are integrated into fixed hardware, and the operator can control the corresponding slave stations by simply touching the touch panel provided in front of the video display. Since the equipment can be selected, it is possible to obtain a master station for remote monitoring and control equipment that can be used for a variety of purposes, while providing operators with the same convenience as with conventional custom-made monitoring and control panels. This has the effect of providing an ideal master station device for a remote monitoring and control device, such as being able to perform control operations while visually checking the diagram of the slave station and the status of the device.
